LOL - I'm gay... I don't mind Ms! After all Lassie was actually a Laddie and nobody knew!
At any rate, I don't care one way or the other, I doubt very much Ms. Manners answers all her questions, and weren't the Landers sisters been for years before their column ended?
What I realized from answering this however, is that I don't have a pair of plexi heeled shoes in my book and this information never got in... an oversight for sure. I am not 100% sure on all the dates, like when lucite was first made but it was somewhere around 1937... I would have double checked if this info got into my book. I can't believe I missed this... However, I wrote the book chronologically and I have to admit I was tired and in a time crunch by the time I got to the 1950s.
